Should 'Hi', 'thanks,' taglines, and salutations be removed from posts?
So you're not supposed to start questions with "Hello guys" or end them with a signature, right? Well, here's an idea: Detect common cases of this and warn the user that this is unwanted cruft.
So, if your question starts with:
...or ends with:
username(likely an indicator of trying to manually sign)
- thanks in advance (this is discouraged, right?)
...then a box pops up that says:
Your question starts with "hello". This is considered unnecessary; please remove it.
Your question ends with your username. You do not need to "sign" your questions; please remove it.
...and so on. It shouldn't be blocking, just informational.
